What Scheepswerf Slob does

Scheepswerf Slob B.V. is a Dutch shipyard established in 1947 (originally as Lasbedrijf J.C. Slob in Sliedrecht, relocated and concentrated in Papendrecht from 1983) that specialises in the design, engineering, and construction of complete, "hot-work-free" steel and aluminium hulls for medium and large luxury superyachts ranging from 40m to 120m+. Since 2002 the company has operated as a 100% subsidiary of Koninklijke De Vries Scheepsbouw B.V. — part of the Feadship group — and holds an exclusive structural position as the sole builder of all hulls for Feadship superyachts built by De Vries. The company also supplies hulls and engineering services to third-party yacht builders including Amels, Oceanco, Royal Van Lent, and Klaassen. Headcount is approximately 175 skilled employees plus a sizeable flexible workforce.

Scheepswerf Slob's core offering is an integrated hull package built in six service lines under one roof: (1) detail engineering using 3D CAD (Cadmatic/NUPAS, Siemens NX, Rhino) and Teamcenter PLM; (2) work preparation creating fabrication work packages; (3) steel hull production in large covered halls; (4) aluminium superstructure construction in dedicated aluminium halls (the second commissioned in 2024) with green and conventional aluminium capability; (5) in-house piping assembly using pipe spool designs from group partner STI; and (6) component installation (inbouw) of oversized items — engines, gearboxes, generators, switchboards — together with hot-work outfit during hull construction. This integrated approach delivers a "hot-work-free" hull, meaning finishing yards can begin their work immediately on receipt. The yard can build up to three hulls simultaneously, each up to 125m in length, with 65+ hulls delivered historically; the largest to date is Project 1010 Feadship Launchpad (118m, 2,456 tonnes).

Commercially the company runs a project-based B2B model: each hull is custom-engineered and custom-priced, with multi-year contract cadence per build, sold direct to enterprise yacht builders and Feadship member yards. There are no off-the-shelf products, no published pricing, and no self-serve or digital channels. Operational partnerships tie the firm into the wider Feadship ecosystem — STI for piping engineering, De Vlijt for flexible staffing, the SYBA vocational academy for talent pipeline — alongside an external co-maker network that supplements production and engineering capacity when needed. The most recent capital investment, the 2024 Rietgorsweg aluminium hall, extends capacity for large superstructure work and signals continued capability investment.

Partnerships

Five partnerships are on record, tiered core and minor.

• Koninklijke De Vries Scheepsbouw B.V.coreOthers · 1 January 2002Shipyard Slob is a 100% subsidiary of Koninklijke De Vries Scheepsbouw B.V. The integration, decided in 1999 and completed in 2002, gave Shipyard Slob access to the broader Feadship ecosystem and drove growth within the luxury yacht building sector. Shipyard Slob builds all hulls for Feadship superyachts from De Vries.
• STI (100% subsidiary of De Vries Groep)coreTechnology or IntegrationSTI provides the routing and pipe sketches for pipespools used in Shipyard Slob's hull construction. Shipyard Slob's work preparation provides work packages for piping assembly, which STI's designs then guide.
• Super Yacht Building Academy (SYBA)coreStrategic or Co-development PartnerSYBA is a collaboration between four leading superyacht hull builders — Shipyard Slob, Mercury Yacht Construction, Zwijnenburg Shipyard, and Bayards — together with Da Vinci College and Metalent. SYBA provides a specialist MBO BBL+ course in superyacht hull construction (Cascobouw Superjachten), combining 3 days per week on-the-job training at a shipyard with 2 days per week theory and practical training. Aim: retain expertise in the Dutch superyacht hull building sector.
• De Vlijt (hiring agency of Feadship companies)minorChannel Partner/ Reseller/ DistributorDe Vlijt provides flexible workers for all ten Feadship locations, including Shipyard Slob. It is the designated hiring agency for temporary staff across the Feadship group.
• Co-makers (external production partners)minorStrategic or Co-development PartnerShipyard Slob can rely on co-makers within and outside the region for additional construction capacity. For Project 1010 (Launchpad), the bow and parts of the aluminium superstructure were outsourced to co-makers. Engineering capacity can also be supplemented by cooperating engineering parties.

Recent moves8 records

Expansion highlights5 records

Broad incumbents

• Lürssen: German-based global leader in large custom superyacht construction (including megayachts >100m, overlapping with Slob's largest projects such as the 118m Launchpad). A broad incumbent offering design, engineering, and full build across multiple yards.
• Benetti (Azimut-Benetti Group): Italian megayacht builder within the Azimut-Benetti Group, with a Custom division comparable to Feadship-class yachts. A broad incumbent in luxury superyacht construction serving the same ultra-high-net-worth clientele.
• Damen Shipyards: Major Dutch shipbuilding group and parent of Amels. Overlaps with Slob in marine engineering, steel/aluminium fabrication capacity, and Dutch superyacht ecosystem context, though Damen's primary focus is commercial and naval vessel construction.
• CRN (Ferretti Group): Italian superyacht builder owned by Ferretti Group, building fully-custom 40–90m yachts in steel and aluminium. Comparable to Slob in build material mix and customer segment, though operating as part of a larger publicly-listed group.

Direct peers

• Oceanco: Major Dutch luxury superyacht builder (60m+ yachts). Oceanco both historically contracted hulls to Slob and competes for the same large custom superyacht build contracts; it represents the most direct competitive alternative for top-end hull construction work.
• Amels (Damen Yachting): Part of Damen and a leading Dutch luxury yacht builder, Amels is both a former customer of Slob (pre-2002) and a competitor for custom superyacht work. Comparable in operating geography and customer segment, with broader product range including the Amels Limited Editions line.
• Royal Van Lent Shipyard: Sister Feadship member yard and long-standing customer of Scheepswerf Slob. Royal Van Lent builds complete Feadship superyachts and historically relied on Slob for hull construction — they sit in the same integrated Feadship/De Vries ecosystem and compete/co-operate on the same class of yachts.
• Heesen Yachts: Dutch builder of all-aluminium superyachts (50–80m). Heesen is a regional direct competitor in the custom luxury superyacht space, focused on fast displacement and all-aluminium builds — directly comparable to Slob's aluminium superstructure capability.

Emerging players

• ICON Yachts: Dutch builder focused on explorer-style and hybrid superyachts. An emerging player with partial overlap to Slob's customer base, particularly around sustainability and unconventional custom builds.

Others

• Bayards Aluminium Solutions: Dutch aluminium fabrication specialist and co-founder of SYBA alongside Slob. Functions as a complementary co-maker/ecosystem partner in the Dutch superyacht hull supply chain, with overlapping aluminium superyacht expertise rather than direct competition.
